Ответ:
The base angle of am isosceles triangle are equal. Let the angles be x, thus;
x+x+48=180 (sum of angles in a triangle add up to 180°)
2x+48=180
putting like terms together we get:
2x=180-48
2x=132
dividing both sides by 2 we get;
(2x)/2=132/2
x=66°
The base angles measure 66°;
also;
∠STR=∠QTR=48/2=24°
